Nolan Dyck is still having a problem:
Hi Bruno,

Thanks for your reply.

Yes, the idea is to model the bubbles as solid particles. The algorithm I
am proposing is this:

A large, finite number of particles are initialized in a cube. These
particles are assigned random velocities and prescribed growth rates based
on a desired size distribution. As the simulation progresses in time, the
particles move around and collide with other particles, each growing
according to its prescribed growth rate. The walls of the cube are
periodic, so any 'collisions' with a wall result in the particle appearing
at the opposite side of the cube. Because the particles are growing,
eventually they will fill the cube and each particle will be 'locked' in
place. At this point further growth in any particles will result in
interference with neighboring particles. The simulation is finished when
the desired particle (or void) fraction is attained and I will have a truly
periodic packed bed (or spherical void phase porous media block).

Would Yade be good for this or no?

Nolan
